The singer, 26, married Sam Cooper at St. James the Great Church in Gloucestershire, England, on Saturday – and the newlyweds are expecting a baby, her rep confirms.

Dressed in a gown with long lace sleeves and a fishtail skirt by French designer Delphine Manivet, the bride was given away by her father, Keith Allen, and then carried a bouquet of white roses as she made her way out of the church with her new husband to a waiting car as a crowd cheered.

"It's beautiful that she is pregnant, and I am very happy for her. She is very happy about that – it is something wonderful," Manivet told British paper The Telegraph. "For me, and for her too, when you're pregnant you want to show that, but also be respectful, so the dress was perfect for her for that moment."

The baby news comes seven months after Allen and Cooper announced the heartbreaking loss of their son.

The wedding, which took place in the village of Cranham in the English countryside, was no secret. Allen's wedding date was leaked to the press by an unknown guest, who sent the save-the-date card to British newspapers in March.

On Friday, Allen and Cooper were spotted arriving at the church for their rehearsal. Allen's dad, an actor and musician, was also spotted with a ukulele – perhaps planning to serenade the happy couple.

Cooper, a decorator and business owner, popped the question during a romantic getaway last Christmas.
